DOUBLE-OVEN STOVE.

Specification of Letters Patent No. 8,332, dated September 2, 1851.

To aZZ whom it may concern Be it known that we, Oonnxn Harms and PAUL V.Zornnn, of Cincinnati, Ohio,have invented new and useful Improvements inDoubleOven Cooking-Stoves; and we do hereby declare the following to bea full, clear, and exact description of the same, reference being had tothe annexed drawings,

making part of this specification, in which drawings Figure l is abirds-eyeview, the stove top being removed, showing more especially thedamper arrangement, as the damper (a) lies on the top of the back oven(6) and shown also in Fig. 2, the damper consisting of a single plateand having leaves (0) to project when desired over the diving flu-es (d)which are immediately back of the fireplace (c) and between said fireplace and the cold-air chamber (7") and shown also in Fig. 2,which liesathwart the stove and arranged so as to protect the ovens from too greatheat at the adjacent portion of their outlines. The damper has also aleaf which extends athwart the stove, to project when desired over thedescending flue (h) which is in the rear of the back Oven. The damper,by the handle projecting through the rear plate of the stove can thus bemade to cover. the diving flues ((Z) or the descending flue (h) atpleasure and thus enable a person to use the front or the back oven asmay be desirable. Fig. 1

also exhibits the fireplace (e) and (the drop and a portion of thehearth plate being removed) the top-plate of the front oven (2') and thefront descending flue Fig. 2 is a central and vertical section in theline A, B, of Fig. 1. In this figure another peculiarity of ourinvention is shown and this consists in the flue (/0) which lies betweenthe front and back ovens and opens directly in the exit flue (Z) of thestove. To effect this purpose the exitflue (Z) is removed from theactual position it holds in the rear of stoves, and is taken up at theside of the stove as seen in Fig. 1. A damper is made to close thecommunication between the boiler flue (n) and the exit flue as seen bothin Figs. 1 and 2. The dotted lines (0) (p) and arrows (9) indicate themode shown in Figs. 2 3 and 5 of taking up the exit flue. The flue (7c)is between the ovens and below the cold-air chamber the bot-tom plate ofwhich chamber is on a level with the top of the front oven, the saidchamber projecting over the same and also under the hearth of the tireplace; receiving cold air through openings (r) in the side plates of thestove and discharging the same at (8) into the flue (0) under and asideof the hearth shown in Figs. 5 and 2. The main draft of the stove passesby the boiler flue down the rear descending flue and thence along thebottom of the back oven, a portion passing up the flue (k) and into theexit flue (Z) shown in Fig. at as described and the remainder passingaround the curved plate (a) as seen in Figs. 2, 3, and l and beingdischarged at ('v) as seen in Fig. 2 into the exit flue (Z).

F 3 is a horizontal section in the line, C, D, of Fig. 2 (the stovebeing turned bottom upward) and shows the curved plate (a), the openingup to the flue shown more clear in Fig. l and the plate (m) which isalso seen in Figs. 2 and 5 and which forces the draft (this plate isalso shown in Fig. 3) of the front flue to the corners of the stove forthe purpose of equalizing the heat, before the draft is led to the issue('22) to be discharged into the exit flue.

The drawings sufficiently illustrate in general the construction of thestove and as it assimilates in other respects to other double ovenstoves, the front oven of which extend under the hearth, it isunnecessary minutely to describe parts and points not claimed.

Therefore having thus fully clearly and exactly described our jointinvention and improvement in double oven stoves wherein the front ovenextends under the fire-place or fire place and hearth as may be desired,what we claim therein as new and desire to secure by Letters Patentis 1. The damper (a) constructed and arranged as described so that oneor both ovens may be used at pleasure.

2. l/Ve also claim the flue between the ovens substantially asconstructed and arranged to communicate directly with the exit flue (Z).

3. We also claim projecting the cold air chamber into the flue under thefireplace and there discharging the received air so as to protect theoven from being over heated at that point.

In testimony whereof, We have hereunto set our hands before tWosubscribing Wit- 1 nesses.
